I’m reviving an old project (started 10 years ago…). By then I stored my assests in .dae format. A sample is available here, it’s hair (see first screenshot with purple background):
It imports pretty well in Blender, so it helps converting the model to an .obj file. The resulting .obj (with .mtl) is available here:
It imports almost perfectly in Unreal. The 2 materials are generated nicely upon import (material 0 has the alpha texture while material 1 has the solid texture). Glossiness needs adjustment to not make it look like plastic but that’s a minor issue.
My issue here is that the alpha channel doesn’t seem to be applied. The strands that finish “nicely” don’t render “nicely”, see second screenshot. We should see the green box through the strands that were circled.
I assigned the “rgba” from my texture sample to the material base color, but that doesn’t help (see screenshot 3).
I’m grateful in advance to anyone stopping by and reading this
